NAME

SYNOPSIS

10       gfs2_grow [OPTION]... <DEVICE|MOUNTPOINT>...
11
12

DESCRIPTION

14       gfs2_grow  expands  a  GFS2  filesystem after the device upon which the
15       filesystem resides has also been expanded. gfs2_grow expands  the  GFS2
16       filesystem  to  utilize any unused space between the current end of the
17       filesystem and the end of the block device.   When  this  operation  is
18       complete,  the  resource  group  index for the filesystem is updated so
19       that all nodes in the cluster can use the extra storage space that  has
20       been added.
21
22       See  lvmlockd(8)  for  the  procedure to extend and refresh the logical
23       volume prior to running gfs2_grow.
24
25       The DEVICE or MOUNTPOINT arguments must be paths  to  mounted  filesys‐
26       tems;  expansion  of unmounted filesystems is not supported.  gfs2_grow
27       need only be run on one node in the cluster.  The other nodes will  see
28       the  expansion  has  occurred  and automatically start to use the newly
29       available space.
30
31       gfs2_grow must be run as the superuser. When the filesystem  cannot  be
32       resized  due to detected errors, gfs2_grow will leave the filesystem in
33       a consistent state.

OPTIONS

36       -D     Print out debugging information about the filesystem layout.
37
38       -h     Prints out a short usage message and exits.
39
40       -q     Be quiet.  Don't print anything.
41
42       -T     Test. Do all calculations, but do not write any data to the disk
43              and  do not expand the filesystem. This is used to discover what
44              the tool would have done were it run without this flag. This op‐
45              tion  can be used to display the current state of a mounted GFS2
46              filesystem.
47
48       -V     Version. Print out version information, then exit.

NOTES

52       Shrinking GFS2 filesystems is currently unsupported.
